Basilisk

The Basilisk is an artificial demon created by Agnus by magically cross-breeding a gun and a dog. It is able to fire its fiery skull from its body like a bullet, and then regenerate a new one. Agnus is able to summon six Basilisks at a time and use them like artillery while in his Angelo Agnus form.

Strategy
Basilisks are swift and agile opponents often able to attack you while in the middle of a combo. Their skulls are easily dodged, but the opposite can be said when they pounce at you. It is recommended to take potshots at them while continuing to dodge their attacks and focus your hits on one Basilisk while still paying attention to the others attacks.
